Possibly a Protea
Thats what I’d say too ......here’s a googled image for you to compare....They are South African flowers - not easy to grow here without a glasshouse. But if you like the flower you could probably find similar in a dahlia or chrysanthemum that you could grow in the garden. BTW Happy 50th to your wife 🥳🥳🥳
Thanks for the good wishes too 🙂
They are popular as cut flowers as they last such a long time.
